xattr -cr /Applications/...ap
codesign --force --sign - /Applications/..app
Gemini
One Final “Safety Net” Command
Sometimes, even after those two, macOS might still block the app from execution due to Gatekeeper’s internal policy. If the app still won’t open, run this:
sudo spctl --add /Applications/YourApp.app
| Command | Primary Function | Why use it? |
|---|---|---|
xattr -cr | Clears Attributes | Removes the “quarantine” flag and the “App is damaged” error message. |
codesign --force --sign - | Ad-Hoc Signing | Re-signs the app locally so it doesn’t crash if the original signature was broken. |
sudo spctl --add | Whitelisting | Explicitly adds the app to the Gatekeeper “Allowed” list without disabling global security. |
spctl --assess -v | Verification | Checks if macOS will currently allow or reject the app before you try to open it. |
sudo spctl --master-disable | Global Override | Brings back the “Allow apps from Anywhere” option in System Settings. |
tccutil reset All | Privacy Reset | Clears permissions (Camera, Mic, Disk) for an app if the “checkbox” isn’t working. |
